EFFECT OF FILLER ON MECHANICAL PROPERTIES AND GLASS TRANSITIONTEMPERATURE OF PULTRUSION EPOXY RESIN CASTINGS

Abstract

Abstract: In order to study the effect of filler particle size and filler type on the mechanical properties and glass transition temperature of pultruded epoxy resin castings, different size, same type of Al(OH)₃ filler and the same particle size, different kinds of filler are added into the epoxy resin in the present study. The results show that the tensile and compressive strength of the pultruded epoxy resin castings with the Al(OH)₃ filler particle size of 5 μm is the highest when the same filling amount, different particle size and the same kind of filler are added. When the same filling amount, the same particle size, and different kinds of fillers are added, the tensile and compressive strength of the pultruded epoxy resin casting body which contains the heavy calcium carbonate is the highest, and the bending strength is not much different. The glass transition temperature of the pultrusion epoxy resin is increased after the addition of the filler, and the glass transition temperature is higher when the Al(OH)₃ filler with a particle size of 1 μm or the calcined kaolin is added.

Key words: filler, epoxy resin, casting body, mechanical properties, glass transition temperature
